It may be caused by unstable processing equipment or tool wear and other reasons, so it is necessary to check the equipment and tools in time and repair or replace them.

It may be due to severe wear of cutting tools or inappropriate cutting parameters, which require timely replacement or adjustment of cutting tools or adjustment of machining parameters.

It may be caused by programming errors, program transmission errors, or programming parameter settings, and it is necessary to check and modify the program in a timely manner.

It may be due to equipment imbalance or unstable cutting tools during the processing, and timely adjustment of equipment and tools is necessary.

The quality and usage method of cutting fluid can affect the surface quality of parts and tool life. It is necessary to choose a suitable cutting fluid based on the processing materials and cutting conditions, and use it according to the instructions.

It may be due to residual stress in the material and thermal deformation during processing, and it is necessary to consider the compatibility between the material and processing technology to reduce part deformation.
